高等生物比简单生物有更多的基因和更大的基因组。这句话听起来太琐碎了,以至于我们不能问这个问题:为什么?但至少有两种不同的答案。或者当需要更复杂性时有增加基因组大小的内在必要性,或者基因组大小由于其他原因而增加,然后使复杂性“锁定”。最近,Lynch和Conery的一篇文章使用了进化种群动力学的论点,提出低种群规模导致更大的基因组。这就为产生更复杂的生物体提供了机会。
Higher organisms have more genes and larger genomes than simple organisms. This statement sounds almost too trivial to ask the question: why? But there are at least two different answers. Either there is an inherent necessity to increase genome size when more complexity is required or genome size increases because of other reasons that then enable complexity to ‘latch on'. Recently, an article by Lynch and Conery, which used arguments of evolutionary population dynamics, proposed that low population size leads to larger genomes. This then provides the opportunity to generate more complex organisms.
